Vintage Sterling Silver Bracelet Faces Tribal Ethnic Vintage 7"

I think this is Carved black onyx but I'm not 100%. Very nice piece I ship daily, 5 days a week! Please see photos for measurements and condition, please ask any measurement questions prior to purchase.  I do not deep clean the jewelry,  especially the vintage. I clean with microfiber cloth.   I do not want to damage it.   I do not leave backs on earrings for sanitary reasons unless in super condition.
